Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
A single spark plug that fails to ignite the fuel-air mixture can cause a halt in the running of the engine. It can result in incomplete combustion and damage to the catalytic converter of the car. Faulty spark plugs can cause the car to exhibit starting troubles.
At the `b` point, partway through the rise in voltage, the spark plug reaches the discharge voltage and a spark is generated between the electrodes. Between `b` and `c` is called the capacitance spark. At the start of the discharge, the spark is generated by the electrical energy stored in the secondary circuit.
